What reptiles live in water and land?

Do crocodiles have osmoregulatory responses to seawater?

Taplin LE, Loveridge JP. Nile crocodiles, Crocodylus niloticus, and estuarine crocodiles, Crocodylus porosus, show similar osmoregulatory responses on exposure to seawater. Comp Biochem Physiol A Comp Physiol. 1988;89:443–448.

What are some types of lizards that live on Earth?

Lizards can include geckos, blue spiny lizard, iguana and the blue-tongued skin. Some examples of turtle and tortoise species are the Galapagos tortoise, box turtle and the alligator snapping turtle.

Why do reptiles go in the sun to cool down?

Since reptiles are cold-blooded, their bodies respond to the temperature of the surrounding environment. When reptiles become too cold, they go out into the sun to warm themselves. Similarly, if reptiles are too hot, they cool down by going into water or getting out of the sun.

How are sea turtles adapted to their habitat?

Forelimbs are modified into long, paddlelike flippers for swimming while the neck and limbs are non-retractile. The shell adaptations necessary for retractile extremities would impede rapid swimming. With the exception of females that come ashore to nest, sea turtles spend their entire lives at sea and are well adapted to an aquatic existence.

How do tarantulas adapt to their habitat?

Arboreal Tarantulas. These tarantulas have adapted to living in trees by developing a lighter, thinner body than their terrestrial relatives, and have longer, more flexible legs for greater agility. Arboreal tarantulas may also live in low-lying vegetation such as bushes or tall grasses, but do not seek cover underground.

What do crocodiles do for the environment?

Crocodiles are also scavengers that feed on dead carcasses found along the waterways, effectively cleansing the environment. Without crocodilians, many ecosystems would suffer. Conant, Roger and Joseph T. Collins.

How do Crocodiles compete for territory?

Crocodiles compete fiercely with each other for territory, with dominant males in particular occupying the most eligible stretches of freshwater creeks and streams. Junior crocodiles are thus forced into marginal river systems and sometimes into the ocean.

Are saltwater crocodiles aggressive to humans?

In the Northern Territory in Australia, attempts have been made to relocate saltwater crocodiles who have displayed aggressive behaviour towards humans but these have proven ineffective as the problem crocodiles are apparently able to find their way back to their original territories.

Why are saltwater crocodiles good swimmers?

You can see why “salties”, as they are often called, dominate both land and water environments. That is because in addition to being excellent navigators across earth, saltwater crocodiles are also champion swimmers.

Are saltwater crocodiles aggressive?

According to biologist Matthew Brien, who led the research, “The saltwater crocodile has a reputation for being one of the most aggressive species in the world as an adult.”

What do you know about lizards?

Known for their beautiful patterns, high intelligence, and fantastic diversity, lizards are some of the coolest reptiles on the planet. But, how much do you really know about these fantastic creatures?

Where do lizards live on Earth?

Lizards are one of biggest, most diverse and widespread group of reptiles found on Earth. They are found on all continents, except Antarctica. Their color, size and diet varies according to different geographical terrains. Lizards have been in existence before the Jurassic era…

What are the adaptations of a sea turtle?

Turtles are reptiles with hard shells that protect them from predators. Turtles spend most of their lives in water. They are adapted for aquatic life, with webbed feet or flippers and a streamlined body. Sea turtles rarely leave the ocean, except to lay eggs in the sand. Click to see full answer.

Do tarantulas live in the desert?

Tarantulas are burrowers and typically live in the ground. There are hundreds of tarantula species found in most of the world’s tropical, subtropical, and desert regions. They vary in color and behavior according to their specific environments.

Are tarantulas nocturnal or diurnal?

Tarantulas move slowly on their eight hairy legs, but they are accomplished nocturnal predators. Insects are their main prey, but they also target bigger game, including frogs, toads, and mice.

How are sea turtles adapted to live in the ocean?

Sea turtles are adapted to live in the ocean, with some unique features that help them to survive in the marine environment. As reptiles, they require air to breathe and land to lay their eggs. However, the majority of their lives are spent underwater.

How do turtles move on land?

Turtles are slow-moving on land, because of their heavy shells; a desert tortoise moves at only 0.22–0.48 km/h (0.14–0.30 mph). By contrast, sea turtles can swim at 30 km/h (19 mph). The limbs of turtles are adapted for various means of locomotion and habits; most have five toes.

Can sea turtles live in freshwater?

Sea turtles can live in seawater with no need for a freshwater source. They obtain sufficient water from their diet and from metabolizing seawater. Like other marine reptiles and seabirds, sea turtles have a salt gland to rid their bodies of excess salt. This gland empties into the sea turtles’ eyes.

What is the function of the limbs of a turtle?

The front limbs provide most of the thrust for swimming, while the hind limbs serve as stabilizers. Sea turtles such as the green sea turtle rotate the front limb flippers like a bird’s wings to generate a propulsive force on both the upstroke and on the downstroke.

Why do tarantulas have hairs on their back?

Tarantulas have developed highly sensitive setae (hairs or spines) on the legs and back which allow them to sense motion, vibrations and even scents. Some species have also developed urticating, or irritating, hairs on the belly. As a defense, these tarantulas kick the urticating hairs off in the face of a predator,…

How many hours a day do crocodiles spend underwater?

Saltwater crocodiles (Crocodylus porosus) spend up to 11 hours a day submerged. Their ability to dive is important to avoid predators, forage for underwater prey, rest and socialise.

How do crocodiles play with each other?

In other instances, the reptiles played with bright flowers, carrying them around in their teeth, and had fun with each other—for instance, by giving their smaller companions piggyback rides. A male crocodile gives a piggyback ride to his lifelong female partner. Please be respectful of copyright. Unauthorized use is prohibited.

Do crocodiles fight to the death for territory?

Mature crocodiles will compete for territory and often fight to the death. Nicknamed ‘Boss’, a large crocodile will have well-established territories in Kakadu, sometimes surviving years of peer aggression to become the king – they are often more than 5 metres long in length!
